ScentScape system adds an olfactory dimension to gaming and home videos

There have been crude attempts at this before, but this device — from, of all people, Scent Sciences — reckons it really can have you smelling napalm in the morning (provided the game you're playing has napalm and mornings).

The ScentScape is a small device that uses "hardware, software & algorithms and chemistry" to mix its cartridges of around 20 unique "flavours" into a distinct smell.
